Review on binifiMux 40pcs M6-1.0mm Black Hex Nuts: High-Grade Carbon Steel Construction for Optimal Fastening by Dave Albright

This product is a complete waste of money. The quality is poor and the screws are difficult to use. Thanks to my knowledge gained in practice with other tools and home improvement products, I found that these screws were not worth the time and effort. The only pro was the quantity for the price, but I would much rather spend a little more for a better product. The cons significantly outweigh the lone benefit. Save yourself the frustration and look elsewhere for better options.
